People who count themselves part of the so-called "professional left" can now wear the slogan, thanks to a new set of shirts and bumper stickers.

White House press secretary Robert Gibbs set off a political firestorm when he told The Hill that members of the "professional left" have been too hard on the White House and that some of them "ought to be drug-tested."

Those people whom Gibbs criticized now have a novel way to get back at the press secretary. A number of new shirts and bumper stickers have been put up for sale by a user on the website The user also sells buttons and T-shirts railing against oil giant BP, which is responsible for the Gulf of Mexico Oil spill.
